I texted a girl that i am interested in, but i have not seen her in awhile.

Hey guys! I need some help. I just texted a girl i was interested in that i have not seen in about a month because of summer school. This week is finals week, so summer school is almost over. I sent her a text a few hours ago.

Me(5:30): Studying hard for your finals dork butt? (Thanks T-mal!)
Her(5:45):Okay, you idiot!
(I have not responded yet, but i am thinking about texting her this)

Me: Wow you are sooo mean. I am not trying to hurt your feelings, but you are trying to hurt mine. =( Btw, how is your English class going?

I was wondering how do i respond and how do i build up to setting up something fun in a week or two after finals week.
